JOHN F. LESLIE, OF SOUTH BEND, INDIANA.

WIRE-JOINT.

SPECIFICATION formingpart of Letters Patent N 0. 756,251, dated April 5, 1904. Application filed June 29, 1903. Serial No. 163,481 (No model.)

To all whom, it may concernn Beit known that I, JOHN F. LESLIE, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Wire-Joints; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in joints for connecting sections of metal rods or wires such as are used in the manufacture of window or door gratings, gridirons, or other open-work structures.

The object of the invention is to construct a strong joint whichpossesses great rigidity and wherein the employment of solder or other cementing material is dispensed with, while none of the metal is wasted in forming the joint.

To these ends the invention consists in mak ing a joint by reducing the end of the rod by forging and utilizing the surplus metal to produce lateral longitudinally disposed extensions on the reduced end, so that when this reduced end is bent around a second rod,with

its inner flat face contiguous to the periphery of the second rod, the lateral extensions will provide a broad grasping-surface which insures stable and rigid joint without the use of cementing material.

For a full understanding of the merits and advantages of my invention reference is to be had to the following description and the accompanying drawings, wherein Figure 1 is a view, partly in elevation and partly in longitudinal section, on the line w m of Fig. 4:. Fig. 2 is a side elevation of the end of one section with the lateral extensions formed thereon. Fig. .3 is a view at right angles to Fig. 2. Fig. 4' is a side elevation of the joint complete, and Fig. 5 is an end view of the reduced section shown in Fig. 2. l

Making renewed reference to the drawings, 1 designates the end of the rod or section from which the eye for grasping a second rod or section is formed. The end of this rod is reduced by forging or rolling, and by such operation there is formed on each side lateral extensions or wings 2, which are disposed longitudinally of the rod, and there is also formed a shoulder 3, in which the extremity of the reduced end engages when the latter is bent around a second rod or wire 4.

For forging the lateral extensions on the end of the rod 1 none of the metal is wasted and an increased gripping-surface is provided. This gripping-surface is made with a flat face 5, while the outer side of the reduced portion maintains its convexity, as at 6, which, to-

gether with the lateral extensions, forms a gradually-increasing bulge, and by maintaining this transverse curvilinear on the outer face of the reduced end between the lateral extensions avery strong and rigid joint is produced. When the reduced end is bent around the second section or rod 4, with the fiat face of the former contiguous to the periphery of the latter and the extremity of such reduced end fitted in the shoulder 3, as shown in Fig. 4, a substantial and rigid joint is formed, the shoulder preventing displacement of the reduced end when the joint is subjected to torsional or tensile strains.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. Ajoint composed of two sections, one of said sections having its end reduced and formed with a shoulder and lateral extensions, said reduced endbeing bent around the other section with its extensions contiguous to the periphery of the other section and its extremity engaged in the shoulder.

2. A joint of the class described, composed of two sections, one of said sections having its end reduced by forging and formed with lat eral longitudinally-disposed extensions and a shoulder at the base of said reduced end, the inner side of the reduced end being flat and engaging with the periphery of the other section, and the outer edge of the extremity of said reduced end being engaged with the shoulder, substantially as specified.

3. A joint composed of two sections, one of said sections having its end reduced in the direction of its length by forging and formed with longitudinal lateral I extensions, and a provide a flat gripping-surface on one side In testimony WhereofIaflix my signature in Wlnch is bent around the other section, the presence of two witnesses.

other and outer side of said reduced end maintaining its transverse curvilinear between the N LESLIE lateral extensions, whereby a gradually-in- Witnesses:

creasing bulge is formed on the outside of the GEORGE OLTSCH,
